There is a new option in the power management system preference to "restart automatically if the computer freezes".
How does this work exactly?
How can the computer check that it is frozen if it is, well, frozen? Is there anything else that it can still do at that point? For example, will there be a log written about this? Can there still be situations when it is so frozen that it cannot restart itself? Is there danger of accidental restarts when it is not really or only temporarily frozen? This does not happen when a single application decides to beach-ball, right?
